update: including UniversalRP (URP) workaround at bottom!
Having this problem?
Looking for a way to make only the UI matches to what is designed in Photoshop? Don’t want artists to change any workflow because you are in the middle of development? Try this.

Visual Effect Graph is so fun to play with! It’s available in 2018.3

If you are using 2019.1+, you might notice there is a big change to the SRP APIs.
I’ve created a new repository and you can grab here. Much cleaner and minimal.
(My playground pipeline)
Here lists out exact what codes enable the Unity feature when making our custom SRP.
*Note that my codes may not be perfectly optimised, but the concept itself won’t change.
(!) Alert: Below information might be outdated. I stopped updating this note after 2018.x releases.
In pipeline code
In shader code
✅ Doesn’t need to specifically care about it in codes. Write the codes as usual.

Direct means CPU tells GPU to execute work, amount of work is given by CPU
Indirect means CPU tells GPU to execute work, amount of work is calculated in GPU

Import time – when you create a .shader file
- compile the shader variants only when needed, etc. platform, variants
Build time – when you build a player
- [level 1] ShaderLab -> glsl or hlsl or …etc
- if platform supports, from [level 2] hlsl -> IL or MetalSL to AIR…etc
- Cache identical shaders under Library/ShaderCache
- compile only not-yet-ever-compiled shaders (variants for this platform only)
Run time – when you open the app
- [level 3] glsl or hlsl or IL or AIR…etc -> driver (GPU bytecode)
- because target device is unknown for PC/mobile at buildtime
- Depends on driver, when to compile these codes e.g. only when it’s used
- use shader pre-warm to “use” shaders to trigger compilation

I know many people are curious about how to make shaders available for Shuriken Particle System to use, the concept is very simple!!

As mentioned, the Lava Flowing Shader has been released for free on Unity Asset Store!
As my knowledge about shader keeps growing slowly, I found that I can blend more than 2 layers of “UV”…..It is because the 2 texcoords limit only limits on input. Your FBX model can only have 2 UV channels but shader can make instances of the 2 UV texcoords and thus let you have more layers of texture blending. I will try to update the package later.
Another package Simple SeeThrough Shader has been released on Unity Asset Store also. Link: https://www.assetstore.unity3d.com/en/#!/content/33924
